PAPER in Journal of Neuroscience

Our article “Task related sensorimotor adjustements increase the sensory range in electrolocation” was just accepted for publication in SFN’s Journal of Neuroscience. This project which I had started during the late stages of my time at Bielefeld University used a classical behavioral paradigm to train Gnathonemus petersii in a object detection task. In contrast to the classical paradigm however, we used videography of the fish and recordings of its electric organ discharge to computationally reconstruct and analyze the sensory input that fish experience while making a decision (2AFC) in the paradigm.
After i had left the project was picked up and brought to the publication stage in a surpreme fashion by Federico Pedraja. He used his strong background in the modelling of electrosensory images and meticulously analyzed both the kinematic and the senosory data for a series of animals.
Doing this we found that the behaivor is purposefully adapted to the sensing task and thereby the effective range over which electrolocation can be used to detect an object is virtually increased. We contrasted this data with electrophysiological estimates of detection performance.
